The geologic features related to convergent boundaries vary depending on crust types. Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by the radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle. [ 2 ]
Three types of plate boundary Convergent boundary Divergent boundary Transform boundary. Tectonic plate interactions are classified into three basic types: [1] Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.
Cartoon of a tectonic collision between two continents. In geology, continental collision is a phenomenon of plate tectonics that occurs at convergent boundaries.Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together.
At a seafloor spreading ridge, plates move away from the ridge, which is a topographic high, and the newly formed crust cools as it moves away, increasing its density and contributing to the motion. At a subduction zone the relatively cold, dense oceanic crust sinks down into the mantle, forming the downward convecting limb of a mantle cell ...
Fold mountains form in areas of thrust tectonics, such as where two tectonic plates move towards each other at convergent plate boundary.When plates and the continents riding on them collide or undergo subduction (that is – ride one over another), the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak ...

All volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell, the 1783 eruption of Laki and the 2010 eruption of Eyjafjallajökull, are caused by the North American and the Eurasian plates moving apart, which is a result of divergent plate boundary forces. The convergent boundary between the Eurasian plate and the Indian plate formed ...
Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges.
